An asphalt composition has a modified asphalt binder. The modified asphalt binder includes an initial binder, an elemental sulfur, a recycled plastic, and a crumb rubber, the crumb rubber including a recycled material. The recycled plastic and the crumb rubber together define a binder modifier. The binder modifier and the initial binder together define an intermediate binder. The elemental sulfur is in an amount of 30 to 50 weight percent, by weight of the modified asphalt binder. The crumb rubber is in an amount of 10 to 20 weight percent, by weight of the intermediate binder.

Asphalt modification with recycled plastic and crumb rubber for paving, roofing, waterproofing and damp proofing

A modular partition system includes a non-metallic polymer frame assembly. Horizontal members of frame sub-assemblies of the frame assembly are slidably engaged such that a width of a rectangular opening of the frame assembly can be adjusted by sliding the first frame sub-assembly and the second frame sub-assembly together or apart. Front surfaces of the frame sub-assemblies include notches on their front surfaces. The system also includes a non-metallic rectangular polymer panels with non-metallic pegs. If the width of the rectangular opening is adjusted to a specified width, the notches and the pegs align and the pegs can insert into the notches, thereby attaching the panel to the frame assembly.
